EV battery health guides

Almost every electric car knows its own battery’s state of health, and most of them will not show it to you. It is rarely on the dashboard, and where it is, it is often rounded, delayed or pinned at a flattering number.

These guides cover one model at a time: where the real figure lives, what it costs to get at, what the tool is actually telling you, and what counts as normal for that car. Pick yours below.
